- the discharge valve 36 is operably coupled to a main drainage line 34 so as to be to control the discharge of water from the main drainage line 34.
- the environment can, for example, be an estuary adjoining a port or rail facility or the like.
- the main drainage line 34 may be fluidly coupled to one or more gross pollutant traps so as to collect spilled materials, stormwater and the like for release into the environment via the discharge valve 36.
- the system 29 furthermore comprises a controller 31 operably coupled to the discharge valve 36. The controller 31 is able to control the discharge valve 36 in use by opening and closing the discharge valve 36.
- the system 29 comprises at least one water quality sensor 33 operably coupled to the controller 31 .
- water quality should not be construed herein with any technical limitations in mind. Rather, the sensor 33 may be adapted to sense any kind of parameter for the purposes of use by the controller 31 for controlling the discharge valve 36.
- the at least one water quality sensor 33 is able to make a water quality parameter measurement of a water quality parameter at an input of the discharge valve 36.
- the controller 31 is adapted to control the discharge valve in accordance with the water quality parameter measurement measured by the at least one sensor 33. Specifically, if the controller 31 determines that the water quality meets certain water quality requirement then the controller 31 may deem the water safe for release into the environment and open the discharge valve 36.
- the sensor 33 may be adapted to measure differing kinds of water quality parameters. However, in a preferred embodiment, the sensor 33 may measure at least one of pH, electrical conductivity/total dissolved solids, oxidation and reduction potential, turbidity, temperature, dissolved oxygen and total petrol hydrocarbons water quality parameters.

- the decision making process for the control of the discharge valve 36 need not necessarily be performed by the controller 31 (being guided by the software instructions) either. Rather, the decision as how to control the discharge valve 36 may be made by another computing device, especially in the embodiment where a potentially identify contaminants is cross- referenced to a manifest database (described in further detail below). A case, the other computing device should be regarded as being part of the controller.
- the controller 31 is adapted to identify the at least one contaminants in accordance with the water quality parameter measurement.
- the controller 31 may be adapted to detect the presence of an insoluble powders in accordance with a turbidity measurement.
- system 29 is configured such that the default position of the discharge valve 36 is closed. Only upon the controller 31 determining the absence of at least one contaminant will the controller 31 open the discharge valve 36.
- the system 29 is configured to release set volumetric amounts of water into the environment or at least a measure the amount of water released into the environment. In this manner, should the system 29 fail to detect a particular type of contaminant, it may be ascertained the exact amount of this particular type of contaminant that has been released into the environment. Having such volumetric information on hand may advantageously be utilised for the purposes of cleanup operations and the like.
- the system 29 may comprise a flow meter or the like adapted to measure flow rate so as to be able to calculate a volumetric amount released into the environment.
- the system 29 may comprise a buffer tank (not shown) which is, in an iterative manner, filled with water, sampled by the system 29, and, if found to meet the required water quality requirements, discharged into the environment.
- the system 29 is adapted to measure a plurality of water quality measurements.
- the system 29 is able to detect a larger number of potential contaminants.
- the system 29 comprises a sensor array 35 comprising a plurality of sensors 33.
- the controller 31 will actuate or initiate a sampling sequence, which returns readings from the sensors 33 of water quality parameter measurements.
- the water quality parameter measurements received from the sensors 33 can then be compared against a range of acceptable water quality parameters to see if it falls within this range. If it does not, then the controller will interrogate a contaminants database to establish what contaminant(s) are in the water.
- the water quality parameter measurements need not be compared against the range of acceptable water quality parameters, and instead the water quality parameter measurements can be used to interrogate the contaminants database as part of each sampling sequence.
- the sensor array 35 comprises eight sensors 33, each sensor 33 respectively adapted to measure pH, electrical conductivity/total dissolved solids, oxidation and reduction potential, turbidity, temperature, dissolved oxygen and total petrol hydrocarbons.
- the controller 31 is able to use a multivariable contaminant "fingerprint" of water quality measurements to provide a more accurate determination of a potential contaminant.
- the system 29 will include a contaminant database (shown in figure 5) against which water quality parameter measurements received from the sensors can be compared in order to identify one or more probable contaminants.
- the contaminant database will be interrogated by the controller using the received water quality parameter measurements to retrieve the probable contaminants.
- an alert signal will be generated by the controller, preferably for display on a display device such as a screen (not shown), the alert signal preferably providing an indication of the probable contaminant.
- the controller 31 may detect water-based paint in accordance with the turbidity, electrical conductivity and dissolved oxygen water quality measurements, and so on and so forth.
- the contents of containers entering a port are usually recorded within a manifest database.
- the manifest database can comprise a record of the contents of each container currently stored at the protected zone, the location of each container and the like. It is anticipated that the manifest database can also comprise a record of past containers that have been stored or transported through the protected zone.
- the system 29 comprises a manifest database 30 or at least a database connection to an external manifest database.
- the controller will then compare the probable contaminants against those known to be stored or transported on-zone, or which were recently stored or transported on the protected zone.
- the system 29 may achieve greater accuracy in identifying a potential contaminant and location of the source on account of the candidates for potential contaminants being confined to those currently contained in containers in the port, or having recently left the port.
- the controller 31 may subsequently retrieve, from the manifest database 30 the cargo manifest currently within the port. Should the cargo manifest show that one of the containers comprises a shipment of wine bottles from New Zealand, the controller 31 can exclude milk as being a potential contaminant, and send out a recommendation signal recommending that the cargo of wine be inspected first.
- the cargo manifest may further comprise container numbers locations and the like such that should the controller 31 determine a particular type of contaminant, the exact location of the leaking container may be identified so as to quickly stem the leak.
- the system 29 further comprises a pressure sensor 32 operably coupled to the controller 31 .
- the pressure sensor 32 is able to measure a fluid pressure at an inlet of the discharge valve 36.
- the controller 31 may be adapted to control the discharge rate from the discharge valve 36 in accordance with the amount of water awaiting release as determined by the pressure. For example, should the controller 31 ascertain from the pressure sensor 32, that there is little or no pressure, such as during dry spells, the controller 31 may keep the discharge valve 36 closed. However, during a thunderstorm event, controller 31 may ascertain the buildup of stormwater awaiting release so as to initiate the sampling and discharge process in the manner described above.
- controller 31 may control the rate of release from the discharge valve 36 in substantial proportion with the pressure as measured by the pressure sensor 32. It should be noted that in certain embodiments, should the above preferred three sample process be too time-consuming in the event of a large build up of stormwater, the controller 31 may be adapted to reduce the number of samples even to a single sample so as to be able to cope with the demand.
- the system 29 a further comprise a rain sensor 33 adapted to measure rainfall amount.
- the controller 31 may take appropriate action to increase the rate of discharge from the discharge valve 36 even prior to receiving notification as to the buildup of stormwater from the pressure sensor 32.
- the controller will be configured to start a sampling sequence at regular intervals. It is envisaged that the rain sensor 33 can also be used in association with a pressure or level reading of the tank or buffer tank. For example where the rain sensor indicates that no rain event has been detected, but the level of the tank or buffer tank is increasing, then a sampling sequence can be started and an alert signal can be generated immediately as the most likely explanation is that there is a leak or spill.
- the earlier results from the sampling sequence could be subtracted or removed from the later results, leaving a subtracted water parameter measurement.
- This subtracted water parameter measurement could then be compared to stored contaminants in the contaminant database in order to establish what the contaminant was that spilled or leaked later than the first contaminant. If the subtracted water parameter measurement is also not recognised after being compared to the contaminants database, then a further alert signal may be generated making the relevant authorities aware of this.
- this later contaminant may also be compared to the manifest database to try and establish the nature and location of the spill or leakage.
- alert signals and/or recommendations signals can be generated, relating to each leakage or spill. In this way, multiple spills may be handled in larger facilities.
- the exemplary control narrative utilises the example of using a control system 29 within the application of a port to sample surface drainage water and stormwater such that if the surface drainage water and stormwater is within specification, allow the controlled discharge of the water into the environment.
- the main drainage line will normally have the main valve (MOV100) normally closed. It includes a pressure transducer to measure water height in the pipe.

- Potable water is to be flushed through the sample line for 1 minute after each 2 min sample is taken via MOV401 & SV402.
- Potable water is to flush the main pipe each time the main valve (MV100) has been opened to discharge, for 5 minutes via MOV401 and SV401 .
